Check Digit Verification of cas no
The CAS Registry Mumber 201293-05-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,2,9 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 201293-05:
(8*2)+(7*0)+(6*1)+(5*2)+(4*9)+(3*3)+(2*0)+(1*5)=82
82 % 10 = 2
So 201293-05-2 is a valid CAS Registry Number.
